To all whom, 11! may concern.-

Be 1t known that 1, JOHN H. Caosrrnr, a

' citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, h ave invented certain new and useful improvements in Apparatus for Manu facturing Glass Articles, of which the follow ing is a specification, reference being had therein to the accompanying drawings, forming part of the specification, in which Figure 1 is a plan View of an a paratus for forming articles of plastic material 7 rovided with my improved measuring and '1llin apparatus. Fig. 12 is a front elevation oi the measuring and filling apparatus. Fig. 3 is a plan view of the driving-gcarinm Fig. 4 is a vertical sectional view on the line IV IV 01 Fig. 1 looking in the direction of the arrow (1. lg. 5 is an enlarged vertical cross-section through the measuringcup on the line V V of Fig. 4., the cup being closed. s'nular view, the cup being open and errauged over one or the molds.

is a vertical sectional view on the linc VJ. ll of Fig. l and showing the cup in filling position beneath the tank-chamber extension. Fig. 8 is a detail sectional view on the line V111 VIII of Fig. 4 looking in the direction of arrow 3).

My invention refers to means for charging a measured quantity of glass into the molds of a glass-pressingapparatus; and it consists oi" a divided cup adapted to he hrou ht into register with the. delivery-opening 0% a sup ply tank or stream and to receive a content thereof, to shear oil any surplus glass, and to finally open automatically over the mold and to discharge the contents thereinto, as shall be more fully hereinafter set forth.

The invention designed to operate in con unction with any suitable glass-pressing mechanism, preferably that class wherein a series 01' molds are carriedupon a rotating circular table, and l have shown it so arranged to operate with such an apparatus is shown and described in my prior applica" tion, iilod June 10, 1904, hearing the serial number 211,904.

Referring now to the (h-swings, represents the carrying-tahle provided with an an nular series of molds 3, mounted upon the table, adapted to he opened and closed at the proper time and to he carried around inter- Fig. 6 is a inittently to bring the molds into register with the filling mechanism and with the plunger, and finally tothe position where the finished article is discharged h'oin the mold, each mold successively occupying corresponding progressive positions. The turn-table 2 is intermittently actuated by any suitable mechanism, such. as is shown in my prior application above referred to, and the charging apparatus (the subject of the present invention) is so located as to bein operative proximity with each one of e series of molds as it comes into position and also in such relation with the delivery-opening of a glassmelting tank or pot adapted to deliver the molten glass into the cups as they are suc cessively brought into register with said openmg.

i represents a vertical rotating spindle intermittently actuated from the main shaft 5 through constantly-running bevel-gears 6 7, shaft 8 being provided with a mutilated bevehgear 9, provided. with a series of segmental teeth 10, adapted to intermesh with corresponding series of segmental teeth 11 of similar gear 12, mounted upon shaft 4. The

operative teeth of these mutilated gears are so arranged that a partial revolution will be imparted to shaft 4 corres ,onding With the desired period of rotation o' a series of carrying-cups mounted in the upper portion, and it will he understood that I do not desire to be limited to any specific number of cups, as. three, but that these may be varied, a correspending variation being made in the driving-gearing, the only essential being that the cup shall he quickly .moved from the receiving position to the discharge position and that it Will be tern orerily stationed at each osition. Upon t e upper portion of SplTKl e 4-, which is mounted no suitable guiding-hearings 13, is secured a spider-frame 14 of any suitable construction, as a wheel, at equidistant portions whereof around its periphery are located measuring-cups A. These cups consist of an upper stationary portion 15, rigidly secured to the frame 14, provided with an interior cavity 16, pre'icraliily flaring somewhat downwardly, as shown, while the bottom portion of the cup is composed of two opposltelydocated divided sections 17 means of suitable hinge projections and tit 820,479
